A nested electronic crane scale weight loading system

Abstract

The invention discloses a nested type electronic hoist scale counterweight loading system comprising an outer ring weight group, an inner ring weight group, an outer ring weight driving mechanism andan inner ring weight driving mechanism; the inner and outer ring weight groups are made to order according to electronic scale detection requirements, up and down displacement of the weight groups iscontrolled via an electric motor so as to realize electronic hoist scale weight loading effects, complex manual operation of a traditional loading mode is not needed, and security and work efficiencycan be ensured. The inner and outer ring weight groups are adopted at the same time; compared with a traditional single weight group mode, the mode of the inner and outer ring weight groups is advantageous in that a large number of weight points are available to choose from, safety can be improved while height of a weight mechanism is reduced properly, and loading work efficiency is improved via synchronous inner and outer ring loading.

Description

technical field [0001] The invention relates to a weight loading system, in particular to a nested electronic crane scale weight loading system. Background technique [0002] At present, the detection of electronic crane scales in our country mainly uses standard weights or "substitution method" for detection. For large-tonnage electronic crane scales, when traditional standard weights are used for loading, the method of manually connecting weights is used. Due to the electronic crane scale detection There are many loading points for medium weights, and the traditional weights are large in size, which leads to difficulty in loading weights, great safety hazards, and low detection accuracy; when the "substitution method" is used for detection, the "substitution method" has strict requirements. If you do not pay enough attention to its detection The particularity. Ignoring its necessary conditions will inevitably cause adverse consequences and bring errors to the test results....

[0002] At present, the detection of electronic crane scales in our country mainly uses standard weights or "substitution method" for detection. For large-tonnage electronic crane scales, when traditional standard weights are used for loading, the method of manually connecting weights is used. Due to the electronic crane scale detection There are many loading points for medium weights, and the traditional weights are large in size, which leads to difficulty in loading weights, great safety hazards, and low detection accuracy; when the "substitution method" is used for detection, the "substitution method" has strict requirements. If you do not pay enough attention to its detection The particularity of the test. Neglecting its necessary conditions will inevitably cause adverse consequences and bring errors to the test results.

At the same time, some manufacturers of electronic crane scales will use a force measuring machine for testing, so that the electronic crane scales shipped out of the factory are too different from the actual working conditions, and there are often various errors, which affect the accuracy of measurement, and cannot be effectively carried out. Traceability, affecting the reliability of value transmission
